Are these a later model that aren't compatible? You can see from the picture that the new ones (top row) can't hook onto the springs supplied on the head mounting plate, whereas one of the old ones has a bend in the wire which I assume is for the coil spring to engage with. This surmise is illustrated in the second photograph.
Hi Uncle B,

Those little coil springs are used on Series 5 and later decks; you don’t need them as you’ve got the tension springs under the deck as you’ve shown.

Remember that you can simply glue new felt to your existing arms; I bought some piano tuner’s felt and use it on all my decks when the old pads are compressed hard or packed solid with oxide dust.

Cheers,
Bill
